Description

  The present invention includes a curtain airbag device that protects an occupant by deploying an airbag so as to cover the inner surface of a vehicle when a vehicle side impact, rollover (rollover), or when these are predicted. It relates to the rear structure of a vehicle.

  A curtain airbag device is known as one of airbag devices mounted on a vehicle, and this curtain airbag device has an upper edge of an airbag folded in a roll shape from the bottom to the upper edge of a pillar of the vehicle. The air bag is inflated by the gas pressure generated by the inflator at the time of a vehicle collision, and the inflated air bag is connected to the inner side surface of the vehicle, specifically the roof trim. It is deployed in the form of a curtain so as to cover a range extending from the side edge in the width direction to a predetermined lower position in the front part of the rear pillar, thereby protecting the occupant from the impact caused by a side collision of the vehicle.

The curtain airbag device was originally developed to protect the occupant from the impact of a side collision of the vehicle, but in recent years it can properly protect the occupant even when the vehicle rolls over. In other words, a curtain airbag device for rollover has been developed.
For example, Patent Literature 1 discloses a curtain airbag device configured to lock a lower portion of a front end of a curtain airbag to a front pillar and to lock a lower portion of a rear end to a rear pillar. According to this structure, the curtain airbag can be held in place even after the curtain airbag is deployed, and the curtain airbag can be prevented from rising after the curtain airbag is deployed. It is possible to prevent the head from being directly struck against the side of the vehicle such as a window or a pillar (trim) or directly from a broken window onto an object outside the vehicle (for example, a road).

  In the curtain airbag device, the curtain airbag is provided between the front pillar and the front pillar trim that covers the curtain, between the roof and the roof trim that covers the roof, and between the rear pillar and the rear pillar trim that covers the roof. It is arrange | positioned so that it may extend.

  By the way, in general, the roof trim is made of a soft material that easily allows the curtain airbag to be deployed in the vehicle when the curtain airbag is inflated and deployed, whereas the front pillar trim and the rear pillar trim are used. Is made of a synthetic resin material that is harder than the roof trim, for example, polypropylene, for example because of the requirement to enable cleaning of these surfaces, and each pillar trim is made of a hard resin. The same applies to a vehicle including the above-described rollover-compatible curtain airbag device.

  Further, there is known a vehicle in which a side window glass is provided between an intermediate pillar disposed between a front pillar and a rear pillar and a rear pillar, for example, between a so-called C pillar trim and a D pillar trim. A roof side trim made of a hard synthetic resin material similar to the pillar trim described above may be provided on the side edge of the roof trim in the vehicle width direction inward of the upper edge of the side window glass. is there. The roof side trim is formed by notching a part of the roof trim and being provided at the notch part. By thus notching a part of the roof trim, it is possible to improve the mountability of the roof trim in the vehicle. . In addition, a roof side trim may be provided for the purpose of improving the appearance from the inside of the vehicle.

  Furthermore, the rear end portion of the roof side trim described above extends from the upper edge portion along the front portion of the rear pillar trim (D pillar trim) to a height position corresponding to the vicinity of the center in the height direction of the side window glass. May be extended downward (the rear pillar trim is cut away corresponding to the rear end of the extended roof side trim).

The clip member 41A of the pedestal 41 is pushed up from below the roof inner panel 50 until the maximum lateral dimension of the clip member 41A exceeds the opening of the ring member 41D. 41A can be locked to the roof inner panel 50.

  5 and 8, the clip member 41A of the pedestal 41 (exactly its longitudinal axis) is the horizontal part 60A of the roof side trim 30 (exactly imaginary line X extending along this). Extends substantially parallel to the direction D extending through the center of the angle α formed between the inclined portion 60B and the inclined portion 60B (precisely, the virtual line Y extending along the inclined portion 60B), and faces the top surface of the base 41 and the base 41. The portion 50B of the roof inner panel 50 is formed so as to extend substantially perpendicular to the direction D.

  Similarly to the pedestals 40 and 41, the pedestal 42 is also provided with a clip member 42A that bends in the lateral direction (internal and external directions) at the top thereof, and one end of the connection band 42C is fixed to the side surface. The other end of the band 42C is fixed to the ring member 42D.

  A D-pillar inner panel 80 (see FIG. 7) is attached to the D-pillar of the vehicle 1, and as shown in FIGS. 5 and 8, the D-pillar inner panel 80 facing the clip member 42 A of the roof side trim 30. A mounting hole is formed, and the ring member 42D is attached to the mounting hole. As shown in FIG. 7, the bracket 26 is also appropriately supported by the D-pillar inner panel 80.

  The clip member 42A of the pedestal 42 also has a maximum lateral dimension in the vicinity of the intermediate portion in the height direction, and the opening of the ring member 42D is smaller than the maximum lateral dimension of the unloaded clip member 42A. The clip member 42A of the base 42 is pushed from the front side in the vehicle front-rear direction of the D pillar inner panel 50 until the maximum lateral dimension of the clip member 42A exceeds the opening of the ring member 42D rearward. Thus, the clip member 42A can be locked to the D-pillar inner panel 80.

  5 and 8, the clip member 42A of the pedestal 42 (exactly its longitudinal axis) is the horizontal portion 60A of the roof side trim 30 (exactly imaginary line X extending along this). Extends substantially parallel to a direction D extending through the center of the angle α formed between the inclined portion 60B and the inclined portion 60B (precisely, an imaginary line Y extending therethrough), and faces the top surface of the pedestal 42 and the pedestal 42. The portion 80A of the D pillar inner panel 80 is formed so as to extend substantially perpendicular to the direction D.

  As described above, the roof side trim 30 is attached to the vehicle body by locking the pedestals 40, 41, 42 spaced in the longitudinal direction of the roof side trim 30 to the roof inner panel 50 and the D pillar inner panel 80. Can do. In this mounting, the clip members 40A, 41A, 42A and the positioning pins 40B of the bases 40, 41, 42 all extend in the same direction, and the ring members 40D, 41D, 42D, and the positioning holes 51 for receiving them also all in the same direction. Since it extends, the roof side trim 30 can be easily attached by simply pushing it up from the vehicle interior toward the roof inner panel 50 and the D pillar inner panel 80 along the direction D shown in FIG.

  When the curtain airbag 20 is inflated and deployed, the roof side trim 30 attached to the roof inner panel 50 and the D-pillar inner panel 80 via the pedestals 40, 41 and 42 has the horizontal portion 60A of the roof side trim 30 in the vehicle. 5 and the inclined portion 60B of the roof side trim 30 receives a slightly downward pressing force toward the inside of the vehicle, so that the roof side trim 30 is generally shown in FIG. It is pressed in the direction D.

  When this pressing force overcomes the holding force of the clip members 40A, 41A, 42A of the bases 40, 41, 42 against the roof inner panel 50 and the D pillar inner panel 80, the clip members 40A, 41A, 42A are respectively roofed. The ring members 40D and 41D of the inner panel 50 are detached from the ring member 42D of the D-pillar inner panel 80. However, since the bases 40, 41, and 42 are connected to the roof inner panel 50 and the D-pillar inner panel 80 via the connection bands 40C, 41C, and 42C and the ring members 40D, 41D, and 42D, the connection bands 40C, 41C are connected. 42C, it is only separated from the roof inner panel 50 and the D pillar inner panel 80 by the length of 42C. Therefore, the roof side trim 30 is not completely removed from the roof inner panel 50 and the D pillar inner panel 80.

  In this manner, the roof side trim 30 moves from the roof inner panel 50 and the D pillar inner panel 80 by a predetermined distance in the vehicle interior direction, so that the curtain airbag 20 is inflated from the space formed thereby toward the vehicle interior. Since the roof side trim 30 made of hard resin can prevent the curtain airbag 20 from being inflated and deployed, the roof side trim 30 made of hard resin can prevent the roof inner panel 50, Since it is not completely released from the D-pillar inner panel 80, it can be avoided that the occupant is damaged by the roof side trim 30 being scattered.

  Further, in relation to the roof side trim 30 being pressed toward the vehicle interior by the curtain airbag 20, the vehicle side edge 30 </ b> A, the vehicle front / rear front end 30 </ b> B, the vehicle front / rear rear end of the roof side trim 30. 30C denotes a bottom surface (side surface of the vehicle interior) of the side edge portion 9A of the roof trim 9, a bottom surface (vehicle interior side surface) of the rear end portion 4A in the front-rear direction of the vehicle at the top of the C pillar trim 4, 71, the movement of the roof side trim 30 may be prevented by the roof trim 9, the C pillar trim 4, and the D pillar trim 5 when the curtain airbag 20 is inflated and deployed. Therefore, the deployability of the curtain airbag 20 can be improved. This can also prevent the hard C-side pillar trim 4 and the D-pillar trim 5 from being greatly deformed or damaged due to the movement of the hard roof side trim 30.

  Further, when the roof side trim 30 is configured only by the horizontal portion 60A, when the curtain airbag 20 is inflated and deployed, the rear end portion of the horizontal portion 60A interferes with the hard D pillar trim 5, or The curtain airbag 20 that is inflated and deployed from the D-pillar trim 5 may be damaged and the fragments may be scattered in the vehicle. In the present invention, the roof side trim 30 is removed from the horizontal portion 60A and from the D-pillar trim 5. It is integrally formed so as to extend (continuously) to the portion or region of the D pillar trim 5 corresponding to the portion of the curtain airbag 20 to be inflated and deployed, and as described above, the entire roof side trim 30 is expanded when the curtain airbag 20 is inflated and deployed. Since it is moved in the direction D, damage to the roof side trim 30 can be suppressed.

  Furthermore, the clip members 40A, 41A, 42A of the bases 40, 41, 42, the positioning pins 40B, the ring members 40D, 41D, 42D and the positioning holes 51 for receiving them are all roofed when the curtain airbag 20 is inflated and deployed. Since the entire side trim 30 is arranged in parallel with the direction D in which the side trim 30 is moved, when the curtain airbag 20 is inflated and deployed (when the roof side trim 30 moves in the direction D), the clip members of the bases 40, 41, 42 40A, 41A, 42A and the positioning pin 40B are smoothly removed from the ring members 40D, 41D, 42D and the positioning hole 51, thereby preventing breakage due to interference between these components and scattering to the occupant.

  The roof side trim 30 is releasably attached to the roof inner panel 50 and the D pillar inner panel 80. When the curtain airbag 20 is inflated and deployed, the roof side trim 30 is separated from the roof inner panel 50 and the D pillar inner panel 80 by a predetermined distance. For example, the means disclosed in Patent Document 2 may be used instead of the above-described structure as a means for moving only.

  Finally, the portion of the curtain airbag 20 facing the hard roof side trim 30 is configured by moving the roof side trim 30 away from the roof inner panel 50 and the D pillar inner panel 80 as described above. The portion of the curtain airbag 20 arranged along the side edge portion 9A of the roof trim 9 pushes the side edge portion 9A of the roof trim 9 away from the vehicle interior. It expands and expands. The portion of the curtain airbag 20 disposed in the hard A-pillar trim 2 is inflated and deployed in the vehicle compartment from between the A-pillar trim 2 and the first-row seat side glass window 10.

The present invention is not limited to the above-described embodiments, and various modifications as described below are possible.
For example, in the above embodiment, although the present invention is applied to a vehicle including four pillars including three rows of seats 6 to 8 and A pillars to D pillars, the vehicle includes two rows of seats and includes three pillars. The present invention can also be applied. In this case, the rearmost C pillar of the vehicle may constitute a rear pillar, and the above-described overall L-shaped roof side trim 30 may be provided on the C pillar (rear pillar) to the B pillar (intermediate pillar).

  In the embodiment described above, the roof inner panel 50 to which the pedestals 40 and 41 are attached and the D pillar inner panel 80 to which the pedestal 42 is attached are configured as separate members, but these are configured as a single member. For example, a part of the roof inner panel 50 may be continuously extended to a position where the pedestal 42 is attached.
